Along these lines, in the initial stage of zeroing work in a independent chuck, I use a regular chuck key but without the cross bar. I work it like a screwdriver and can reach around the back of the chuck quite well. It reduces the amount of chuck turning required and prevents me from over tightening the jaws during the adjustment period. Obviously the jaws have to be tighter than that for turning so they get snugged up evenly and gradually before starting the lathe.
